Advanced numerical simulations and simulators

We need simulation tools for understanding new phenomena as well as designing devices based on the understanding. Simulations that we are carrying out include photonic simulations, gain modeling, carrier transport, and thermal simulations. Especially, the 3D vectorial simulation is numerically most demanding, since the feature size of nano-structured devices is much smaller than the entire device size. We have developed two numerically efficient 3D photonic simulators, based on modal expansion and quasi-normal mode picture. The simulators and simulations of our interest are listed below:

  • Numerically efficient 3D photonic simulators
  • Spatio-temportal rate equations
  • Self-consistently coupled laser simulators of photonic, carrier transporting, and thermal models
